摘　　要：郴州—钦州铀成矿带紧邻桃山—诸广山花岗岩型铀矿成矿带,其成矿前景越来越受到关注。分析了郴州—钦州地区花岗岩型铀成矿地质条件,认为本区断裂控矿明显,富铀岩体发育,特别是其北部地区花岗岩型铀矿成矿条件较好。通过对航空放射性异常、水系沉积物、化探异常等要素的叠置分析,指出了郴州—钦州地区铀资源量扩大的前景,认为骑田岭岩体是本区寻找花岗岩型铀矿的有利地段。Chenzhou-Qinzhou uranium metallogenic belt was closed to the Taoshan-Zhuguangshan granite-type uranium metallogenic belt. It was an important ore-prospecting area for granite-type uranium deposit. The authors analyzed geological condition of mineraliza- tion of granite-type uranium deposit in Chenzhou-Qinzhou area, and suggested that ore-controlling fractures and uranium-enriched igne- ous rocks were well developed in the area, especially in the north part of the region which had favorable metallogenetic conditions for granite-type uranium deposits. Based on the overlap analysis of factors of geophysical and geochemical prospecting like aero-radioactivi- ty anomaly and geochemical anomaly of the stream sediments, the authors discussed the prospecting potential of uranium resources in Chenzhou-Qinzhou area and indicated that the Qitianling intrusion was of good prospecting perspective for searching granite-type urani- um deposit.
